Puntos clave

To evaluate microvascular parameters for diffusion MRI signal in solid tumours using simulation techniques.
Developed a simulation model to assess vascular diffusion MRI signal.
Estimated metrics q_m and A_NB for tissue characterization.
Applied methods for in vivo evaluation to capture overall trends.
q_m and A_NB emerged as leading metrics for assessing microvasculature.
In vivo estimates captured biologically plausible contrasts.
Findings support the potential for these metrics in future studies.

Resumen

Simulation-based modelling of the vascular dMRI signal suggests q m qₘ and A N B ANB as the most promising metrics for tissue microvasculature characterisation. Their estimation in vivo appears feasible to capture general trends, and demonstrates contrasts that are biologically plausible, encouraging their usage in future studies.
